LAST SUNDAY'S 9 PM AIRING OF DEXTER (1.876MM) WAS THE HIGHEST-SINGLE TELECAST ON SHOWTIME SINCE 2004, BREAKING LAST WEEK'S RECORD SETTING PERFORMANCE (1.676MM).

After weeks of investigation and preparation, Dexter (Michael C. Hall) cleverly imbeds himself into Trinity/Arthur Mitchell's (John Lithgow) seemingly idyllic world. "His cycle is over. It will be a while before he kills again," rationalizes Dexter. "He's not an immediate threat and I have so much to learn." Meanwhile, Dexter's carefully constructed facade of a home life begins to come apart as Rita insists on marriage counseling. Will Dexter be able to maintain his suburban pretense along with his Trinity obsession? "I will kill him. I need to, but right now I need to save my family first."
